喀麦隆西南省的两个地区此前曾报告过并殖吸虫病，包括库佩山和蒙达尼疫区。本研究的目的是调查 Meme 区 Kumba 城郊地区肺吸虫病的存在情况和流行病学，该地区距离 Kupe 山焦点约 50 公里。昆巴周围 5 个村庄的几所公立小学的学生接受了寄生虫学和临床调查，以寻找肺吸虫病的体征和症状。鉴别诊断中还检查了结核分枝杆菌。解剖了五个村庄邻近溪流的淡水蟹，检查并殖吸虫囊蚴。在所有五个村庄总共 1482 名学生中进行了检查，根据是否存在一种或多种肺吸虫病体征或症状，招募了 309 名学生（147 名男性和 162 名女性）参加这项研究。在所有五个村庄的小学生的粪便和/或痰液中都发现了非洲并殖吸虫卵，总的非洲并殖吸虫患病率为 2.56%。各村之间疾病患病率无显着性差异（X2=8.36，P=0.08）。在有肺吸虫病症状的学生中，非洲并殖吸虫卵的患病率为 12.3%（309 名学生中有 38 名）。男性感染率高于女性（17.0% vs 8.0%），但差异不显着（X2 = 5.76，P = 0.16）。 38例并殖吸虫卵阳性受试者均出现咳嗽症状，23例（60.53%）主诉胸痛，16例（42.11%）咯血。粪便检查还发现一些肠道寄生虫，包括蛔虫（29.45%）、毛虫（6.47%）、美洲板虫（2.27%）、粪类圆线虫（1.62%）、蛲虫（0.65%）和溶组织内阿米巴（4.53%）。没有发现结核分枝杆菌病例。在总共 85 只解剖的螃蟹（Sudanonautes africanus）中，6.02% 感染并殖吸虫囊蚴。除了之前描述的库佩山和蒙达尼两个肺吸虫病疫源地外，在昆巴镇城郊地区发现了本土肺吸虫病病例，使西南省成为目前喀麦隆肺吸虫病最流行的地区。
Paragonimiasis have previously been reported in two zones of the Southwest Province of Cameroon including the Kupe mountain and Mundani foci. The aim of this study was to investigate the presence and epidemiology of paragonimiasis in the peri-urban zone of Kumba, Meme Division, located about 50 km away from the Kupe mountain focus. Pupils of several government primary schools in 5 villages around Kumba underwent both parasitologic and clinical investigations in search of signs and symptoms of paragonimiasis. Mycobacterium tuberculosis was also searched for in the differential diagnosis.Freshwater crabs from neighbouring streams in the five villages were dissected in search of paragonimus metacercariae. Out of a total of 1482 pupils examined in all five villages, 309 individuals (147 males and 162 females) were recruited for this study based on the presence of one or more signs or symptoms of paragonimiasis. Eggs of Paragonimus africanus were found in stools and/or sputum of pupils from all five villages, giving an overall paragonimus prevalence of 2.56%. There was no significant difference in the disease prevalence between the villages (X2 = 8.36, P = 0.08). The prevalence of Paragonimus africanus eggs amongst pupils with symptoms of paragonimiasis was 12.3% (38 of 309). Males were infected more than females (17.0% versus 8.0%), but the difference was not significant (X2 = 5.76, P = 0.16). All the 38 paragonimus egg positive subjects presented with cough, 23 (60.53%) complained of chest pain while 16 (42.11%) had haemoptysis. Stool examinations also detected some intestinal parasites including Ascaris lumbricoides (29.45%), Trichuris trichiura (6.47%), Necator americanus (2.27%), Strongyloides stercoralis (1.62%), Enterobius vermicularis (0.65%), and Entamoeba histolytica (4.53%). No case of M. tuberculosis was noted. Out of a total of 85 dissected crabs (Sudanonautes africanus), 6.02 % were infected with paragonimus metacercariae. In addition to the two previously described paragonimiasis foci of Kupe mountain and Mundani, the identification of autochthonous cases of paragonimiasis in the peri-urban zone of Kumba town, makes the South West Province the most endemic zone of paragonimiasis in Cameroon at present.
